Five minutes of processing the local features of a Navon letter causes a detriment in subsequent face-recognition performance (Macrae & Lewis, 2002). We hypothesize a perceptual after effect explanation of this effect in which face recognition is less accurate after adapting to high-spatial frequencies at high contrasts. Five experiments were…

In four experiments, college students were presented with lists of either Armenian or English letters on a tachistoscope. The data indicate that extensive practice may be a necessary condition for capacity-free processing but may not be a necessary condition for involuntary processing. (Author/RD)

Letter encoding is typically viewed as an automatic process that is both obligatory and interference free. In these experiments, either familiar or non-familiar primes produced significant amounts of interference even when subjects were trying to ignore the visual input. Early perceptual components of encoding are both obligatory and resource…

Familiar letter sequences in noncued portions of a tachistoscopic display were shown to reduce accuracy of partial report. Findings suggest that familiarity may automatically direct attentional resources to a particular spatial region. Such attentional capture may be disruptive if the material is presented at another location. (Author/RD)

High frequency words typed in normal and alternating case were presented tachistoscopically in the fovea and parafovea to children and adults. Dependent measures were percentages of letters and words correct. Few differences between age groups were found. Serial position curves also showed similarities across grades in the parafoveal information…
